This is one of the many things I received when my grandfather passed. Some I know what they are some I do not. This falls under the I do not category.
I am hoping someone can give an educated guess on what it might be.
The whole thing comes apart. Its grooved and notched so everything fits very tightly. It has a steel shaft going half way through to the lower piece.
Inside the lower piece are 4 small steel rings with holes in them.
Just so you have a little insight on where the item came from. My grandfather worked for the NRL for 30+ years different fields including, fracture
mechanics, hypervelocity research, rocket development and in the space systems division. Hope this info helps.
